scalur® – pickled hot-rolled steel with very tight thickness tolerances

For maximum efficiency in component production

Our hot-rolled strip for cold-rolled purposes: scalur® is suitable for direct processing, in the same way that a cold strip would be. .

Our hot-rolled strip for cold-rolled purposes: scalur® is suitable for direct processing, in the same way that a cold strip would be. Its thickness tolerances are as low as ± 0,05 mm while a very flat profile is maintained.

The pickled hot-rolled steel scalur® is manufactured at the continuous strip plant (CSP) in Duisburg. The flat strip displays uniform properties and a consistently high product quality over the entire strip length and width. Because of the very thin bandwidths that the CSP produces, scalur® is especially suitable for stamped, pressed and drawn parts. And due to the very tight tolerances that this product offers, the ordered thickness can be reduced, meaning that you will receive additional meters of strip with every order.

scalur®’s very tight tolerances fall far below the usual tolerances of hot-rolled strip. The calculation for our micro-alloyed steel S700MC serves as an example. The standardized tolerance thickness for micro-alloyed steel according to DIN EN 10051 amounts to +/- 0.29 mm at an ordered thickness of 2.10 mm. In comparison, the thickness tolerance of scalur® S700MC only amounts to +/- 0.05, thus being much tighter. Accordingly, the ordered thickness is reduced to 1.86 mm when ordering scalur®. This results in 11 percent less weight and a high potential for lightweight construction, especially when using higher strength steel grades. In addition, up to 120 extra band meters can be allocated per order.

Hot-rolled strip for cold-rolled purposes

With scalur®, thyssenkrupp Steel is proud to offer a hot-rolled strip with a homogenous microstructure for high ease of processing. The quality of our first-class hot strip is comparable to that of a cold strip. Yet, scalur® is much more affordable. Processed in one combined casting and rolling production step, this hot strip has very low levels of sulfide inclusions. At the same time, scalur® is very low in profile and suitable for direct processing. Another benefit: scalur®’s consistently high quality leads to a shortened setup time at the production plant and hence to less downtime and an increased production rate.

Good for the environment and for your wallet

Continuous strip plant
Continuous strip plant in Duisburg Bruckhausen.

We produce scalur® at the continuous strip plant in Duisburg Bruckhausen. The CSP combines the normally separated production steps continuous casting and hot rolling: The steel streams fluidly out of the CSP and is cut and then cooled off directly afterwards. The rather thin band withs as well as the uniform properties of scalur® can, among others, be attributed to this special production process at our thyssenkrupp Steel facility. Thanks to the innovative way of manufacturing, we do not need to further process the hot strip at the cold strip mill. This means that you will get the same excellent product quality at a lower price point. Moreover, not only does your wallet benefit when you order scalur®, but so does the environment: When comparing the production process of the CSP to that of a conventional hot strip production, the CSP production saves more than 60 percent energy.
